This invention relates to a door stop adapted to bear'on opposite sidesof an open door and on a floor under the door, to coniine the es dooragainst accidental movement from any 5, opened position. Y

The invention is embodied in improvements renderino' a stop of thischaracter more desirable in certain respects than others hereto' sa foreprovided. Y

Of the accompanying drawing forming a part of this specification Figures1 and 2 show in perspective a door stop embodying the invention and aportion of Y a door, the door a shown by Figure 1 being called a highhung door, while that shown by Figure 2 is called a low hung door.

Figure 3 is a bottom View` of one of the feet shown by Figures 1 and 2.A

The same reference charactersjindicate. the

- same parts in all of the figures.

My impro-ved door stop is adapted for use with either a high hung doorvwhose lower end may be an inch or vmore above the floor', or a low hungdoor whose lower end may be d lapproximately half an inch or less abovethe iioor.`

The stop comprises a pair of blocks 12 hav-- ing flat oblong facesarranged to bear on a iioor, lopposed inner sides arrangedv to faceopposite'sides of a door, and a neck 14 rigidly attached to the blocksand spacing them apart with their inner sides substantially parallelwith each other. The blocks and neck may be of cast metalcast in onepiece7 or the blocks may be cast upon the end portions of aseparatelyformed neck or otherwise united` thereto. n .y

' The neck 14 is formed toenter the space between the lower end of ahigh hung door M D l (Figure 1)y and a floorsupporting the stop, 55 sothat the stop may be located on the floor at any desired distancelinward from the swingingpedge ofthe door. ,Y Y f The neck Yis locatedatV one side of the lonn gitudinal centers of the blocks so that itconstitutesone end of a door receiving'recess between the major portionsof the,blocks,"and isadapted to-abutthe swinging edge of a low hung doorD (Fig. 2) in said.r ecess,'sov 7 5 that although the neck cannot belocated in the spacel under the door D', them'ajor portions of the block12 may be located at oppof site sides of said door in position to opposeaccidental swinging thereof. The neckfis movable inwardly under'a highhung door to locate, all portions of the blocks beside thedoorasindicated by Figure 1, so thatthe blocks do not project from theyswinging edge of the door, and do not constitute an lobstruction atsaid swinging edge. y. To preventrattling contact betweenvthe sides ofthe door and the inner sides of the blocks 12 I provide said inner sideswith'antirattling buffers arranged to Contact noise lessly withoppositesides of a doorvportion so between the blocks. `'Each buffermaybe one side of a loop 17 of elastic or other suitable materialextending vertically across the mid length portion of the block sides,the loops being confined against edgewise `vdisplacementwby the blockspreferably by grooves 18 fo-rmed in* the upper'edges of the blocks. Thebuffers are formed to project'outwardly from the sides of theV blocksand prevent'conf` tact .of any portion of the blocks with the door.y jTo cause a frictional engagement between the blocks and the floor Iprovide feet. 19 of rubber or other suitable .frictional matei rialunited to the ends of the loops and bearing on and covering the bottomsofthe blocks', said feet .being adaptedto frictionallyenf' gage a Vfloorand oppose movement of. the blocks thereon. The bottomsurfaces of saidfeet are provided with obliquev grooves 19a ifif forming obliquecorrugations (Fig. 3) having flat faces bearing on a iioor. The obliqueedges of said faces are longer than they would be if the corrugationswere not oblique, and therefore have a more effective engagement withthe floor.

Each foot and loop may be molded in one piece, or the ends of the loopsmay be united by vulcanization to opposite edges of the feet, the loopsupstanding from the feet, and being normally contracted so that they maybe stretched and allowed to spring into the grooves 18. The loopsconline the feet against the bottoms of the blocks 12.

To additionally secure the feet 19 to the blocks I provide thekbottomsof the blocks with sockets 2O receiving stud ortions 21 of the feet, sothat endwise and ec gewise displacement of the feet are prevented.

To enable the stop to engage both sides of doors of dierent thickness Imay provide one of the blocks 12 with va clamping member movablerelative to the block to bear on one side of a door andv clamp theopposite side thereof against the other block.

Said member preferably includesv a bell crank lever including arms 24and 28 and fulcrumed at 25 in arecess 26 in one block. The arm 24 has ayface 27 which is movable by an operator through the arm 28, to exertpressure on one side of a door as indicated by dotted lines in Figure 7.The face 27 is preferably of rubber adapted to frictri'onally engage thedoor, and has a tongue 29 entering' a groove 30 in the lever.

I refer to provide the loop 17 with verticalijy arranged beveledv edgefaces 31 on one or both of its sides, thus preventing the formation ofshoulders liable to catch on or interfere with a door when' the stop isbeing moved into engagement therewith. Although the faces 31 arerequiredl only on the inner sides of the loops I prefer to provide themon both sides, because by sodoing I am enabled to apply the feet andloops to the blocks without taking care in locating beveled faces on theinner sides of the blocks.
